Application led September 1,9, 1914. Serial No. 862,626i

T o all lwhom t may concern Be it known that we, IVAR F. VVARME and JOHN C. TALIAFERRO, citizen-s of the United States, residing at Syracuse, inthe county of Onondaga, State of New York, and residing at the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Multiple- Spindle Double Seamers, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention rela-tes to new and useful improvements in an apparatus for attaching the end to a can body, and more particularly to an apparatus for forming a double seam for joining the can end to the can body. While our improved apparatus is particularly adapted for joining the can end to a filled can body, it may also be used for securing the bottom end ,to the can body.

An object of the invention is to provide in an apparatus of the above character an end seeming machine wherein a plurality of rotating chucks are mounted and are held substantially fixed against radial movement relative to the carrier andwherein a seaming member is associated with the carrier and. so positioned relative to the rotating chucks that as the carrier rotates the can ends which have been seated in the can bodies will be moved into contact with theseaming member and withdrawn therefrom during a partial rotation of the carrier.

A further object of the invention is to provide an end seaming machine of the above character wherein the seaming member is in the form of a rotatable seaming roll having a seaming groove formed therein and this seaming roll is not only eccentrically mounted relative to the rotation of the carrier, but means is provided for adjusting the eccentricity of the roll so as .to vary the pressure of the seaming roll against the can A further object of the invention is to provide an end seeming machine of the above character wherein the adgusting means for the seaming roll is so constructed that the eccentricity of the roll may be varied without shifting the angular' osition of maximum pressure of the seaniing roll against the 'can endu l A still further object of the invention is to provide an end seaming machine of the above character whereinthere is a can body receiver and can end support associated with each chuck and wherein means is provided for placing a can end on each can end support while the carrier is rotated.

A still further object ofthe invention is to provide an end seaming machine which consists of two rotating carriers, each of which is provided with a plurality of rotate ing chuc (s and cooperating can supports, and wherein one carrier has a seaming roll operating simultaneously upon a plurality of can ends for performing the first operation of joining the end to the can body and wherein the other rotating carrier has aseamiiig roll associated therewith operating simultaneously upon a plurality of can ends for performing the second operation in joining the end to the can body, together with means for transferring the cans from one carrier to the other.

A further object of the invention is to provide an apparatus of the above character having two rotating carriers with means for supporting the seaming rolls of .the respective carriers whereby the axes of said rolls may be adjusted relative to the axis of their respective carriers for varying th'e pressure of the seaming rollson the can ends' during the seaming operations.

These and other objects will in part be obviousand will in part be hereinafter more fully disclosed.

Fig. 32 is a diagrammatic view showing a modified arrangement of the closing machines.

The invention consists generally in providing an apparatus for attaching the ends to cans wherein an end is attached to a can body by a double seam. As shown in the drawings, two end seeming machines are used in conjunction, one of which operates to form the first operation in joining a can end to a can body and the other performs the second operation in joining said can end to the can body. rl`hese end seeming machines are substantially alike with the eX- ception that associated with one of the machines is an end feeding mechanism Whereby can ends are fed to the rotating carrier therefor and supported in proper relation to the can bodies so that they may be seated therein as the can bodies and the ends are chucked for rotating the same.

Each end seaming machine consists of a rotating carrier on which are 'mounted a plurality of rotating chucks and coperating can supports. rFhese chucks are carried by spindles which are mounted in spindle carriers and these spindlecarriers are in l,turn fixed to the carriers .so that they are placed si'de by side and held romany substantial movement radial to their carriers. @n each carrier is a seaming roll which is eccentrically mounted relative to the axis of the carrier, and this seeming roll is so dis posed relative to the, traveling chucks that the can ends are successively brought into engagement therewith and moved out of contact with the seaming rollas the carrier ll@ rotates. Means is provided for adjusting the eccentricity of these seaming rolls whereby the pressure of the rolls against the can ends may be varied. rllhe two carriers ice preferablyV rotate in the same direction and are slightly spaced so that a transferring mechanism may be placed between the carriers for receiving the cans from one carrier and placing the same on the other as the carriers rotate.

These end scanning machines are especially designed forsecuring the closing end on a filled can and also designed so that 4the lled cans may be received directly from a lling machine which is mounted upon iat the same supporting base as the end seaming machines. The can support of the tilling machine is located in the same plane as the can support of the closing machine so that the lled cans may he transierredrom tu@ one support to the other as said can supports are rotated and in order to facilitate this transfer, the can support of the filling machine rotates in a direction opposite to the direction of rotation of the can support of the closing machine.'

Referring more in detail to the drawings, the can machine consists of a bed plate 1 on which is mounted a filling machine which may be so constructed as to lill the cans in 'two operations, placing in the cans in one operation the solidparts and in another operation the liquid parts. In Fig. 1 of the drawing, we have indicated at A the first operation lling machine and at B the second operation filling machine. The details of this illing machine have not been illustrated except to show in full lines the can support 2 of the second operation filling machine and the receivers 3 for holding the cans as they are being filled. This support 2 rotates in the direction of the arrow as indicated in this figure. Also shown in this figure are two end seaming machines indicated at C and D, respectively. A transferring mechanism for transferring the cans from one end seeming machine to the other is indicated at E, while the end feeding mechanism for feeding the ends to the closing machine C is indicated at F.

The two end searning machines C and D are similar in construction except Vas to a few details and, therefore, a descri tion of one of these machines will answer or the other.

The end seaming machine indicated at C is the first operation machine, while the end seaming machine indicated at D is the second operation machine. These two end seaming machines will be described as one and like numerals a plied-to the parts reerred to. The di yerences, however, between the two machines will be pointed out in connection with the detail description.

Mounted on the bed plate 1 is a supporting base 4 from which rises a column 5 on which is mounted a rotating carrier 6. This rotating carrier consists of a lower turret 7 and an up-per turret 8. These two turrets are splined together so as to rotate as one. The turrets are supported on ball bearings indicated at 9 and 10.l

Mounted on the lower turret are a plurality 'of can supports 11.

ing plate 12 which is secured to a spindle 13. This spindle is mounted in a sleeve 14 which extends into a recess in a supporting slide 15. A nut is threaded on the lower end of the spindle and a ball bearing 17 serves to support the rotatable plate 12. The thrust plate 12a rests directly on the bearing 17 and spring 12b engages suitable sockets in the supporting plate and the thrust plate thus providing a yielding support for the can. The lower turret is Each of theseA can supports consists of a rotatable supportlteeth 21. The plates 20 are also formed with gear teeth 21 and these gear teeth serve as a means for rotating the turret. The plates 20 are bolted in place by suitable bolts 22 and the gear teeth are cut after the plates are liXed to the turret. The means for rotating the turret will be described later.

The supporting slide 15 carries a stud 24 at its lower end and this stud is provided with a roller 25 which engages a cam groove 26 in a collar 27. The collar 27 is splined to the supporting base so that it is held from rotation and as the turret rotates therefore, the roller 25 will be caused to travel in the groove 26. The collar 27 is shown in plan view in Fig. 14, and in side elevation in Fig. 15. The lower part of the collar 27 is provided Iwith a thread 28. The supporting base 4 is also threaded at 29. These threads 28 and 29 are respectively right and left hand threads. A ring 30 engages the threads 28 and 29 and by turning this ring the collar 27 is raised and lowered. -The ring is provided with suitable recesses 31 whereby it may be rotated. The groove 26 which engages the roller 25 is formed with an upper section 32 and a lower section 33. As the turret rotates the roller 25 will pass from one section to the other of the cam groove and thus raise and lower the can supports. The purpose of this movement of the can support is to raise the filled can into contact with the can end which is to close the same and bring the can end into Contact with the rotating chuck for clamping the can body and can end and rotating the same as it is presented to the sea'ming roll. By shitting theI collar 30 the position of the supporting plates v12 may be varied. By this shifting of the plates, cans of varying heights may be closed on the machine. j Mounted on the turret and forming a supportingtable is a filler plate 34. This plate is provided with openings 35 adapted to receive the can supports 12. The plate may be secured to the turret by suitable screws passing 'through openings 36. As clearly shown in Fig. 17, these filler plates may be removed and replaced by a filler plate of greater thickness as indicated in dotted lines in this figure when the can support 12 is adjusted to a new position.

The filler plate forms a table, the upper surface of which is iush with the upper surface of the can supports when said can supports are in their lower position. This permits the filled cans to be readily slid on to the table and on to the can supports without spilling the contents thereof.

Cooperating with the can support 12 is a rotary chuck 38. This rotary chuck is secured to a spindle 39 which is in the forni of a sleeve. The spindle 39 is journaled in a spindle carrier 40. Said spindle is provided with a ball end thrust bearing 41 adj acent its lower end and a ball lateral thrust bearing 42. Said spindle is also provided with an end thrust bearing 43 and a lateral thrust bearing 45a adjacent the upper end thereof. Fixed to the upper end of the spindle is a pinion 45. This pinion meshes with a gear 46. The gear 46 is splined to a shaft 47 which is mounted in a suitable bearing 48 carried by the supporting base 4. The shaft extends upward through the column 5 and is mounted in a bearing 49 at the upper end of the column. This shaft is rotated by a suitable gear 50 at the lower end thereof. The gear 50 meshes with a gear 51 secured to a shaft 52 which is mounted in a bracket 53 carried by the bed plate. The gear 51 meshes in turn with a gear 54, and this gear 54 carries also a. beveled gear 55 which meshes with a beveled gear 56 on the main shaft, and the main shaft is rotatedby a suitable motor` 57 which is mounted on the supporting bed. The gear 54 is attached to the central shaft of the first operation machine, while the gear 50 is attached to the central shaft of the second operation machine and, therefore the shaft of the second operation machine is driven from the shaft of the first operation machine through the intermediate gear 51.

The rotating spindle which carries the chuck is in the form of a sleeve and extending1 through this sleeve is a rod 58 which carries a seating'pad 59 at the lower end thereof. This seating pad is normally housed in a recess inthe under face of the chuck.. This rod 58 is held from rotation but is reciprocated longitudinally lin the spindle sleeve. This is accomplished hy a sleeve 60 which is fixed to the upper end of the rod 58 and carries a roller 61 which runs in a cam groove 62 in a cap plate 63. The cap plate is carried hy a sleeve 64 which surround-s the upper end of the shaft 47. The cap plates of the two machines are joined by a bar 65, which bar is bolted to the cap plates hy bolts 66. This bar encircles the project ving sleeve 64 of the cap plate 63 and one ca pplate locks the other through this connect ing bar from rotation. There is a collar 67 secured to the upper end of the shaft 47. The collar 69 is also provided with an. arm 68. This arm 68 is forked at its outer end so as to form a recess 69 adapted to receive a lug 70 lprojecting from the adjacent collar 60. These arms 68 through the forked construction of the outer end thereof and the interlocking lug 70 lock all the rods against rotation, hut inasmuch as .the side walls of the lugs 70 arevertical, they permit each rod recaer-e chuck and the seating pad rests against the can end until the can body is raised and Iforced on to the can end, that is the can end is seated in the can body, after which the seating pad rises with the can end and can body holding the can end seated until the can end is received by the chuck. The seating pad is then withdrawn from contact with the can end and held out of contact therewith while the chuck is rotating the can end and can body and forming the end seam. After the end seam is formed the seating pad moves down with the can support and becomes a stripperfor stripping the can end from the chuck. The cam groove 62, therefore, is formed lwith an upper and lower level section., the lower level section operatingl to hold the seating pad in lengagement with the end during the seating thereof while the upper level holds the seating pad out of engagement with the can end. There is also in this cam groove a knock out section which operates the seating pad to strip the can from the chuck. The only difference btt-Ween these cans. in the rst and second Boperation machines is that in the second operation machine this lower level is omitted for the reason that when the cans are fed into the second operation machine the ends are secured thereto and therefore, no seating operation of the pad is necessary. ln other words the seating pad in this machine is solely a stripper for stripping the can from the chuck.

The spindle carriers are in the form of sleeves with suitable recesses formed therein for the hearings for the chuck spindle. The mountings for these spindle carriers are shown in detail in Figs. 6 and 7. Each spindle carrier is provided with a rearwardly extending web 71 which lits into a recess 72 in the upper turret 8. Adjacent the upper end of the spindle carrier is a erforated lug 7 3. bracket 74 is secure by a holt 7 5 to the upper face of the outer turret 6, and this bracket is provided with spaced arms 76 which receive the lug 7 3 and a pintle 77 passing through the arms 7 6 and the lug 73 forms a hinged connection for supporting the upper end of the spindle carrier. The spindle carrier at the lower end is secured to the turret hy helm 78 and 79. These bolts extend through perforated lugs Sdprojecting from the spindle carrier 40. Each holt is threaded into the turret and is lill@ Lacasse provided with a limiting collar 8l. The lugs 8O are recessed at 82 to receive these limiting collars, and these recesses are slightlyv this machine7 as shown in Fig. l2, are solid and firmly hold these spindle carriers against their seats on the turret.

ln the second operation machine, however, these spindle carriers should yield slightly to permit the side seam to pass the seeming roll without undue pressure thereon. This is accomplished by the construction shown in Fig. 1l. The cap plate 83 is recessed on its inner face and a yielding washer 85 is interposed between this cap plate and a washer 86 which bears against the outer face of the lug 8G. This yielding washer 85 permits a slight outward movement of the lower end of the spindle carrier, the upper end of the spindle carrier swinging about the hinged support therefor.

his spindle carrier not only serves as a means for supporting the spindles orthe chucks but also serves as means Igor supporting the can ends as a means for supporting vthe receivers for the can bodies which centers the same underneath the chuck. To this end, the spindle carriers project downward below the chuck, see Figs. 8 and 9. rShe lower part oi the spindle carrier is formed with a can receive-r 87. rlfhis receiver has an inwardly projecting face 88 which is curved to conform substantially to the curvatureof the can body and the front side is open so that the can body may be fed into the receiver. rlhe receiver above the projecting surface 88 is cut away, as at 89, to form suilicient space for the flange of the can body. Above the receiver is a can end seat 90. rlhe spindle carrier is formed with a flat projecting ledge 9i on to which the can ends are fed and from this projecting ledge the can ends are moved back on to the can end seat 90. lirectly beneath the can end seat is a. tapered opening 92. This can end seat is below the chuck and the spindle carrier is cut away. at 93 to form a clearance space in which the chuck rotates.

The spindle carrier is cut away at 911i 'to permit the seeming roll to project thr ugh and engage the can end when the same is engaged by the chuck. The can ends are ied on to the can end supports after which the can bodies are ted into the receivers and then the can bodies are raised into engagement with the can ends and the can ends carried into engagement with the chucks which rotate the can ends and can bodies as they are now `engagement with the rotating chuck.

clamped between the rotating chucks and the can supports, and as they are rotated they are gradually carried into engagement with the seaming roll.

rlheone difference between the spindle carriers in the first and second operation machines as to the features just described, consists in the fact that in the second operation machine there is no seat for the can cud and the spindle carriers are projected downwardlv solely for the purpose of providing a receiver for the cans which o crates to center the can underneath the chuc is. As the cans are received into the second operation machine with the ends joined thereto, there is no purpose in the can end supports or tapered rin except to guide the can into rlhe seaming roll is indicated at 95. Said seaming roll surrounds the central column and also the lower turret and is formed with a seaming groove 96 which is of uniform cross section throughout the entire circumference of the seaming roll. Said searning roll consists of a supporting sleeve 97 from which projects a rib or disk 98 having the seaming groove 96 iormed in the outer face thereof. rlhis rib or disk 98 is intermediate the ends of the sleeve 97. t

At the inner face of the sleeve 97 is located a roller bearing 98. The rollers of the roller bearing are mounted in sui-table plates 99. Above and below the ends of the sleeve 97 are ball bearings 100. Between the roller bearing 98 and the turret 7 are two rings 101 and 102. These rings are shown in detail in Figs. 2, 4 and 18 to 21, inclusive. rThe inner surface oi' the inner ring OQ is concentric to the axis of the rotatin carrier and is fitted to turn freely on the lower rotating turret 7. 'l he outer surface of this ring, indicated at lB, is eccentric to the axis of rotation of the carrier. rl`he inner surface of the outer ring 101 which contacts with the surface 103 is also eccentric to the axis of rotation of the carrier or lower turret, while the outer surface 104 ot the outer `ring is eccentric to the inner surface of this .outer ring. 'lhe roller bearingsv engage the outer surface of the outer ring. The inner ring is provided with a projecting ila ige 105, wnile the outer ring is `provided. with a projecting flange 106. The langes are Jformed with spaced grooves 107 `and 108, respectively. These grooves may be graduated or provided with suitable indicating mar-ks.

lleneath the rings is a holder 108. This' holder w8 rests on a ledge on the lower tur.- ret 7 and the rings and holder are placed between this ledge and the lower end .of the upper turret 8. A collar 109 is threaded on to the upper end ci the outer ring and overlies'the bearings for the seeming lroll. The helder 108' is provided with an outwardly projecting arm 110 which is suitably bolted to the frame of the machine so as to prevent the holder from rotating. This lholder is provided with a groove 111.

A locking plate 112 is formed with a rib 113 which is adapted to engage the grooves in the flanges of the rings and the groove 111 in the outer edge of the holder 108. A screw 114 passes through said plate 112 and clamps the same to the holder 108.

From the above construction, it will be apparent that the seaming roll is mounted so that it may rotate freely about the rings 101 and 102, but owing to the eccentric surfaces of these rings the axis of the seaming roll is eccentric to the axis of the rotating carrier. lnasmuch as the rotating chucks and coperating-can supports are mounted to rotate about axes which are substantially radially fixed, the seaming roll may be adjusted so that as the carrier rotates, the can ends will be caused to engage the seaming roll and move out of engagement therewith. The eccentricity of this seaming roll may be varied by adjusting the rings 101 and 102. This is accomplished by removing the plate 112 and turning the rings until the proper grooves are brought into register with the Vgroove 111, after which the plate is replaced.

By adjusting both of the rings and by adjusting the same in opposite directions, the axis of the seaming roll may be shifted toward and from the center of the carrier in a radial direction, that is, without shifting laterally the position of the maximum pressure. By adjusting one ring alone, or by adjusting both rings in the same direction, the position of maximum pressure may be varied. The only difference between the seaming rolls in the first operation machine and in the second operation machine resides in the shaping of the groove. These rolls are in each instance similarly mounted and similarlyadjusted.

The cans are transferred from one seaming machine to the other by the transferring mechanism indicated at E. Between the supporting bases of t e two machines, there is a supporting 'brac et 53 in which the shaft 52 is mounted. This bracket carries a table 115 on which is mounted a supporting and guiding plate 116 which is shaped to fill the space between the'rotating tables of the end seaming machines so that a can may be moved from one machine on to this supporting .plate and from theA supporting plate on to the table of the other machine. The upper face of this plate is kept substantially flush with the upper face of the filler plate of the end sea-ming machines. This can be accomplished by changing the plates At the upper end of the shaft 52 is loosely mounted a rotating disk 117 which has segmental pockets 118 shaped to conform to the can bodies. These pockets form of the disk in effect a star wheel. Secured to the disk is a gear 119. This gear meshes with a gear 120 on a vertical countershaft 121. A gear 122 is connected to the gear 120 and run` ning idle on the shaft 121 meshes with a gear 123 `which is splined to the shaft 52. These gearsl are so proportioned' that the timing of the travel of the can body on the plate 116 is substantially the same as the travel of the can body when on either carrier. Also splined to the shaft 52 is a gear 124 and this gear meshes with the gear teeth 21 on the carrier of each end seaming machine. The rotation of the shaft 52, therefore, will cause the two carriers to rotate in unison and each in a counterclockwise direction as viewed in Fig. 1. The guide plate 116 is provided with curved projecting arms 125 and 126 which extend respectively over the supporting tables of the carrier. When the can reaches the arms 125, it will be moved gradually forward through the action of the rotating star wheel and the rotatingcarrier on to the plate 116. The rotating star wheel will carry the can along the plate, and the guide rail of the plate, together with the arm 126, will direct the can so that it is moved into the receiver of the second operation machine.

As above noted, the speed of the star wheel is such that the travel of the cans while in the end seaming machines, and from oneE end seaming machine to the other is uniform.

The means for feeding the can ends' on to the can end supports of the first operation machine C is indicated at F in the drawings. The intermediate frame forming the bracket 53 has an extension 127i On this extension are mounted two stack holders 128 and 129. The can ends are stacked in these holders. Each holder consists of a base ring 130 and spaced rods 131 which are mounted therein. This base ring is .raised from the support 132 attached to the upper end of the extension 127 so as to permit a slide 133 to pass 4beneath the same. This slide carriesk a separating plate 134.

As clearly shown in Fig. 25 of the drawings, when the slide moves forward, the separating plate 134 Will separate the lowermost can end from the stack and will force the same from the stack holder on to the supporting ledge of the spindle carrier 40 and part way on to the can end seat for the can end. As the carrier rotates, a yielding guide finger 135which is fixed to the supporting plate 127 engages the can end and crowds it back on to its seat directly underneath the rotating chuck. here is a reciprocating slide 133 for each stack holder. These slides are .mounted so as to reciprocate in guiding grooves in the upper face of the supporting plate 132. A yoke 136 projects underneath the supporting plate 132 and reciprocates back and forth on said supporting plate. l This yoke is bolted by suitable bolts 137 .to the slides 133. Mounted in the extension 127 "is a shaft 138. This shaft at its lower end carries a gear 139 which meshes with a gear 140 carried by said extension, and the gear 140 meshes with the teeth 21 of the rotating carrier of the second operationmachine. At the upper end of the shaft 138 there is a fiange141 which is fixed to the shaft. Freely mounted on the shaft is a disk 142. This disk and fiange are provided with suitable hardened sleeves 143 into which is adapted to be placed a pin or nail 144. The disk 142 carries a roller 145 which engages a cam groove 146 formed in the yoke 136. This cam groove is so shaped that while the shaft 138 rotates at a uniform speed, the slides for conveying the can ends to the carrier will be quickl moved forward to project the can ends fiom the stacks on to the rotating carrier. yThe purpose of the connecting pin 144 is to provide a breakable connection in the operating mechanism for the end feeding devices so that if for any reason the can ends become stuck, the pin will ,break and thus prevent the breaking of any part of the operating mechanism.

The end feed is so timed .that a can end will be taken from each stack and simultaneously moved forward `on to the can end seats of the first operation machine and when the next two receivers are in front of the stack holders, two more can ends will be delivered from the stacks on to the can end seats of said receivers. f

The operation of joining the can ends to the can bodies will be made clear from the diagrammatic views contained in Figs. 26 to 31 inclusive. The path of travel of the can bodies is indicated by the broken line and the arrows in Fig. 31. In full lines is indicated the surface of the seaming roll. When a receiver of the first operation machine is at the radial line a, the can supports are at their lower level and at this point the can ends are fed on to the can end supports. The upper surface of the table of this end seaming machine, and the upper surface of the table of the filling machine are in the same plane, and a guide rail 145%v operates to crowd the cans from the receivers 3 of the filling machineinto the receivers of the end seaming machine.

At the radial line b, Fig- 31, the filled can is fully seated on the can support and the can support is raised through the action of the fixed cam 26 on the roller 24. Prior to the lifting of the filled cans the seating pad is lowered into engagementl with the can end on the can end support.

In Fig. 26 of the drawings, I have shown diagrammatically a can body being raised e of the carriers of the two machines.

and the seating pad being lowered so as to contact with the can end and supportthe same while it is being seated in the can body. After it is seated in the can body, as shown in Fig. 27, the seating pad retracts and allows the can end and canv body to be raised and chucked as indicated in Fig. 28. This all occurs at or near the radial line b.

When the radial line c is reached the can end begins to make contact with the seam' ing roll. This is brought about through the eccentric positioning of the seaming roll. The contact will be first very light and this will increase to a maximum pressure which rolls the flange of the can end and the flange of the can body into the vfirst `operation of joining the end to the body. j

When the radial lined is reached the can end is free of the seaming roll' and soon after this position is reached the can support drops to its lower position so that the can bottom is flush with the table of the carrier. The arm 125 now engages the can and plate 116. The star wheel 117 which is positively driven engages the can and assists in carrying the same along the gui e rail on to the supporting plate, transfers 1t acrossthe supporting plate and lonto the receiving table of the second operation machine. In Fig. 29 of the drawings, we have shown the position of the seaming roll when finishing the seam. After the seaming roll is out of contact with the same and when the can support is lowered, the seating pad is given a downward push which knocks the can from the chuck, as shown in Fig.30. This occurs at or near the radial line d.

The operation of the ysecond operation machine is similar to that above described. After the can is fully seated on the can support, it is raised so as to cause the can' to engage the chuck. This occurs at the radial line As the carrier rotates the end seam will make contact with the seams ing roll, engaging the same lightly first and the pressure increasing to maximum pressure. This is due to the eccentric seating of the seaming roll relative to the path of travelof the chucks. After the seam is formed, the can end will be gradually withdrawn from the seaming roll and at the radial line e, Fig. 31, itwill be o'ut of contact with the seaming roll, after which the can support is lowered and the seating pad is given a knocking movement to strip the can from the chuck. The closed cans are removed from the second operation machine by the engagement'of the same by the arm 110 of the holding plate 108.

The carrier of each end seaming machine is provided with a groove which engages a rib 147 on the actuatin gear 124. This rib serves to determine t e proper alinement There ltransfers the same on to the supporting
